While trying to edit the POSTACK1 template for an auto-reponder list, one of our listmasters received the following error: Error - template TPLADDERR not found A configuration error was detected in the CGI script; the TPLADDERR template could not be found. Error - invalid parameter An invalid parameter was passed to the CGI function. Please report this error to the webmaster and make sure to specify the full URL that led to this message. Repeated attempts to change the template eventually work. Does anyone know what may be causing this problem? Thanks. We're using LISTSERV Classic 1.8e on Solaris 8. Alex Willman Princeton University
